This 1997 Puget Sound Regional Council study examines the financial feasibility of acquiring and redeveloping properties negatively affected by major regional transportation facilities, including Sea-Tac International Airport, the Auburn Rail Yard, and a proposed Everett HOV facility. It evaluates potential funding mechanisms—such as a state-financed revolving fund or public/private partnerships—to convert noise-impacted land within the 65–75 DNL noise contours to compatible non-residential uses. The study covers roughly 100 acres across three case-study areas and was initiated under Regional Council Resolution A-96-02 adopted in July 1996.

A study commissioned by the Puget Sound Regional Council to assess the financial feasibility of establishing a funding mechanism for acquiring and redeveloping properties adversely impacted by regionally significant essential public facilities. The study examines case study areas near the Auburn Rail Yard, Sea-Tac International Airport, and the proposed Everett 112th Street SE HOV Lanes

June 30, 1997 letter from Washington Governor Gary Locke to U.S. Department of Transportation Secretary Rodney Slater, reaffirming and superseding the December 20, 1996 letter from Ecology Director Mary Riveland to Dennis Ossenkop. Constitutes state certification required under 49 U.S.C. 47101 et seq. that the Sea-Tac Airport third runway development project will comply with applicable

A June 1997 transmittal from the Port of Seattle Engineering Department to Alaska Airlines' Peggy McCloskey forwards final bid bioassay results for the Arco Hoecust Safewing MP IV 1957 Green product. The enclosed Laboratory Report from Bio Research Laboratories, Inc. documents an Acute Oral Rat Toxicity Test performed for MultiChem Analytical Services, testing the Green Safewing MP IV substance at a dose of 5000 mg/kg. The report, dated May 21, 1997, was directed by Warren C. Ladiges, DVM, and signed off by President and Scientific Director John J. Majnarich, Ph.D.

This 1997 Final Supplemental Environmental Impact Statement (SEIS) examines the environmental effects of proposed expansion plans at Seattle-Tacoma International Airport, including construction of a new third parallel runway, terminal improvements, and parking upgrades. The study was prompted by faster-than-expected growth in air travel demand during the mid-1990s, which exceeded earlier forecasts and required updated analysis of noise, air quality, wetland, and community impacts. The document was jointly prepared by the FAA and the Port of Seattle to ensure the proposed developments met federal and Washington State environmental policy requirements.

This technical report supplements the Final Environmental Impact Statement for Seattle-Tacoma International Airport's Master Plan Update, focusing on construction impacts related to the proposed Third Runway and associated projects. It analyzes fill material requirements estimated at 17.25 million cubic yards, haul routes, and truck traffic volumes, noting that the construction timeline was extended from three to five years, which reduced the number of average daily truck trips compared to earlier estimates. The report examines both on-site and off-site material sources and assesses potential traffic congestion impacts on regional roadways during the construction period.

This document is part of the Final Supplemental Environmental Impact Statement for Seattle-Tacoma International Airport, addressing public comments on aviation demand forecasts and runway capacity planning. It explains how the 'Do-Nothing' and 'With Project' (Third Runway) alternatives were evaluated based on projected passenger and operations data through 2010, noting that the existing airfield has a maximum capacity of 460,000 annual operations. The document also acknowledges the inherent uncertainty in long-range aviation forecasts and clarifies that neither NEPA nor SEPA require the use of worst-case data in environmental reviews.
